This afternoon a flock of about 6 Dusky Woodswallows were hawking along Whiskers Creek Road (about 200m outside my GBS site).

In terms of GBS observations this coincides nicely with the expected upturn in number of observations.  A graph is attached: note that this shows the raw number of observations rather than the F% value, since the two lines are similar and this one is slightly simpler to plot.  I have also extended the graph to show that the observations (after the initial 'surge") are less consistent than was the case for the Noisy Friarbird.
